HAND TACKING TOOL.

SPEGICFICATION forming part of Letters Patent No. 652,167, dated June 19, 1900. Application filed June 20, 1898. $erial No. 683,976. (No model.)

To a, whom it may concern:

Be it known that I, THOMAS COWBURN, a subjectof the Queen of Great Britain,residing at Gloucester, England, have invented a new and useful Hand Tacking-Tool for Use by Upholsterers,Oarpet-Placers,Bootmakers,Label- Attachers, or the Like, (for which I have applied for a patent in Great Britain, No. 3,788, dated February 15, 1898,) of which the following is a specification.

This invention relates to a hand tackingtool for use by upholsterers, carpet-placers, bootmakers, label-attachers, or the like, and has for its object to construct a tool-for ininstance, a, pair of pincers or a hammerwhich carries a quantity of loose tacks designed by the pressure of a trigger o1- thumblever to be delivered from a tack-carrier to the nose or projection of the pincers or hammer forming the tool and either to be forced into the material in position to be driven by a blow from the hammer-face or to be delivered and retained with the point protruding from the said nose, so that when the said tool is pressed toward the material to be tacked the tack-point is forced into the material and remains in position to be either wholly or partially driven in, as previously explained, the said tool being also adapted to be quickly and easily supplied with a freshly-chargedtackcarrier.

In the accompanying drawings, Figure l is a front view of a hand tacking-tool made according to the invention, the said tool being in the form of a pair of pincers. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal section through the tack-carrier and the upper jaw of the pincers. Fig. 4=is an elevation of the greater portion of the tool seen from the opposite side to that shown in Fig. 2. Fig. 5 is a sectional side elevation of the tool, showing the manner in which it is used. Fig. 6 is a section on the line 6 6, Fig. 4:. Figs. 7, 8, and 9 are a front elevation, side elevation, and plan, respectively, of the tack-carrier. Fig. 10 is a section of the front part of the tool, showing how it is used when the pincers grip the material to be tacked. Fig. 11 is a sectional elevation showing the invention applied to a hammer and Fig. 12 is a sectional plan thereof, the section being taken on the line 12 12, Fig. 11.

Referring to the form of my invention shown in Figs. 1 to 10, in which I have shown it applied to a pair of pincers, a and h are the two levers forming the upper and lower handles and having the lower and upper jaws a and b, respectively, and being pivoted together by a joint-pin 0, having a central hole, in which the lever-pin 0 works. The upper jaw b is provided with a tack-carrier holder comprising two lateral plates or flanges d d, secured to or made in one with the said jaw b and having a central slot or opening (1 closed by a spring-strip d The upper surface of the upper jaw b that is to say, the bottom of the space inclosed by the two lateral plates d and dis grooved, as shown at (1, Figs. 1, 3, and 5, the said groove being designed to serve as a guide for the tack-point when the tack is being ejected, as hereinafter described. The spring 01 is kept in position by a plate at, coveringthe front central opening (1 and held in position by the catch cl. To the upper end of this plate (1 there is attached a spring (V, which bears against the upper end of the spring=strip d and normally holds it against the open end of the tack-carrier, hereinafter described. The said plate 01 serves 'to take the pressure on the spring (Z and prevents the head of the tack forcing the said spring away too much.

The plate cl is longer than the plate d and is provided with an overhanging strip or roof 02 to which is attached 'a spring c, resting upon and adapted to be raised by the front spring d and serving for guiding the tacks and preventing them from being jerked out of the tack-carrier. This spring 6 has a peculiar undulating motion imparted to it, caused by its coming into contact with a projection on the overhanging strip.

The tack-carrier isadvantageously formed of a plate f, bentto a \l or U shape, Figs. 7, 8, and 9, so that the upturned edges or sides form a groove or receptacle f for the tacks f which can slide along it. The said carrier f is provided with a handle f and is heldbetween the lateral plates d and d at the front end, and at the rear end it is held by a pin or catch f and spring f to facilitate its quick removal and replacement by another when requiredfor instance, when emptied of tacks. The tack-carrier f is provided with a slit or hole f at the front end, into which can pass a tack divider and retainer f formed of a spring piece or plate, one end of which is attached to the plate (1 and the other end formed to pass through the slit or hole f in the tack-carrierf and divide the front or end tackfrom the rest by entering between them, so as to retain the second tack just below the head thereof. This retainerf is forced into the slot f by a sliding piece g, which also has a pin g engaging with a forwardly-projecting hook portion d of the spring at, so as to press forward the top end of the spring 01 when it is slid forward, and thereby release the disengaged tack. The sliding piece g is guided along the side of the lateral plate (1 in a guide g secured to the lateral plate d, and receives its motion froma lever hereinafter described.

g is a spring for normally holding the slide g in its rearmost position.

71. is the tack-ejector, the said ejector being curved, as shown, and also preferably formed 1 tacking arrangement as applied to ahammer, the principle being exactly similar to that above described and the construction only to match the bottom of the groove. It con sists of a rod with a bifurcation or slot h at the rear end, with which a pin 71 on a lever h engages. The lever h is fixed on the pin 0, which passes through or works in the stud c, by means of which the two jaws a and b are hinged together, so that the said jaws can be operated without affecting the tack-ejector mechanism, and vice versa.

'6 is a link one end of which is pivoted to the lever it near the fulcrum thereof and the other end of which is hinged to a thumb-leverj, pivoted atj to the lower handle or lever 1). As will be clearly seen, the depression of the said thumb-leverj when grasping the pincers, as illustrated in Fig. 5, will move forward the ejector h along the groove 61 for ejecting a tack, as hereinafter described.

j is a spring forreturning the thumb-lever to its normal position-that is to say, the position shown in Figs. 2 and 4, The front spring d performs various f unctions-that is to say, it retains the tacks in the tack-carrier while the tack divider and retainer is withdrawn, it moves or raises the front edge of the first tack-head to assist in bringing it out of the tack-carrier, it guides or keeps the tack in the groove during its forward and down- Ward movement, and retains it in position at the nose or end of the groove for entering the material to be tacked.

The tool is employed as follows: The material which is to be tacked down is, for eX- ample, gripped by the jaws a b of the pincers, as shown in Fig. 1O, and the thumblever j is depressed by the thumb, as ind icated in Fig. 5, so as topress forward the upper end of the lever 77.3, and thereby slide forward the ejector h from the normal position (shown in Figs. 2 and 4) and eject the tack which has been released from the tack-carrier and allowed to drop in front of the said ejector, as hereinafter described. The lever in its forward movement strikes against the rear end of the slide g, as indicated in Fig. 5, andpushes the same forward in its guide 9 The forward movement of the said slide 9 forces the spring-plate f forming the tack dividerand retainer, through the slit or hole f in the tack-carrier f, so that the said retainer passes between the first and second t-acksthat is to say, separates the front tack from all the rest. The forward motion of the said sliding piece gthen pushes forward the upper end of the front spring (2 as above mentioned, thereby releasing the front tack,which drops into the space bet-ween the two lateral plates d d, as clearly shown in Fig. 5, the said tack being then retained in the said space until the ejector has been withdrawn and again pushed forward, when it is forced in or through the material to be tacked or is held so that by pressing forward the nose of.

the tool it is forced into the material and driven in by means of the hammer a on the lower jaw a.

In Figs. 11 and 12 I have illustrated my being altered to adapt it to the different tool,

I in these figures the parts corresponding to the similar parts in Figs. 1 to 10, inclusive, ex-

cept that capital letters are employed in Figs.

11 and 12 and small letters in Figs. 1 to 10.

In the arrangement shown all the mechanism is fitted inside the hammer-shaft K and 'head K.

The head K is made with a front space for receiving the released tacks, and

also with a curved guide for the ejector II, which is operated through the medium of the link L, lever L, link L lever L and link L from the lever If, which is pivoted to the I hammer-shaft at L and is normally held in its uppermost position bythe spring L The tack-ejector is provided with a stop H, which strikes a lateral sliding piece G, so as'to force the spring piece or retainer F through the slitor hole F in the tack-carrier F and separate the front tack in the said carrier from the remaining tacks in the manner hereinbefore described, and also to release the said front tack by pressing forward the front spring D and raising the top spring E, also 'in the manner hereinbefore described.

To refill the tack-carrier, any ordinary means may be used, such as a hopper with a couple of plates forming a groove .for the tacks to slide in and against which the tackcarriers can be held to be refilled.
